Tanzania
Clove hills drop to a channel 800 metres deep, and the wall dives start at shore.
The clove hills drop green to a coast of mangroves and coves, and just offshore the shelf gives out: the Pemba Channel falls 800 metres close enough to shore that the walls begin where the snorkelling ends.
Pemba is the Zanzibar archipelago's quieter, greener island, its hills still scented with the clove harvest and its coast fringed by mangrove channels and reef walls that serious divers cross oceans for, hammerheads and pelagics riding the deep channel. There is no package strip; village life and a handful of lodges set the pace, reputable dive operators read the currents, and the dry months, June to October with July to September's clearest water, are the season. The island's plates run to octopus in coconut milk and fragrant pilau rice.
Solo
Experienced independent divers can enjoy Pemba after confirming reputable boats, current currents and personal limits.
Couple
A pair can combine clove country with reef or mangrove time, adjusting water plans when the Pemba Channel changes.
